Related to albedo: solar constant


n. pl. al·be·dos
1. The fraction of incident electromagnetic radiation reflected by a surface, especially of a celestial body.
2. The spongy white tissue on the inside of the rind of citrus fruit.

Mounting structure heights should be raised to allow the rear surface to capture additional diffuse albedo light.
Remote sensing techniques make it easier to estimate snow-water content from measured albedo in inaccessible mountain areas.
So, it's more than a little important to know how the ice's reflectivity, also called albedo, is changing.
To model drought-induced changes in albedo and surface energy balance as well as the interaction between albedo and the atmosphere in a semiarid region (i.e., the Loess Plateau) two severe drought cases (2001 and 2005) were selected.
The Albedo 100 spray is highly reflective of lights during darkness and can be sprayed on to almost any surface.

From there, it's a positive feedback loop, the researchers explained: The reduced reflectivity (or surface albedo) enhances precipitation, which fuels plant growth, which reduces albedo, and so on.
Just as the Red Planet began to inch into the evening sky in late May, ahead of its closest opposition since 2003, a swath of bright orange dust clouds covered the dark albedo feature Mare Acidalium.
"The concentration of black carbon deposits found in the Andean snow implies a reduction in the reflectivity or albedo of the snow of less than 2.0 percent," he said.
The heat island effect can be counteracted slightly by using white or reflective materials to build houses, roofs, pavements, and roads, thus increasing the overall albedo of the city.
Quantifying radiative forcing and building energy demand impacts due to pavement albedo changes is essential to understanding the role of concrete pavements in keeping urban areas cooler and forestalling global warming, say Xin Xu, Dr.
